Karlskrona is a beautiful town in the south of Sweden. It's most known for the fact that it throughout history has been an important town for Swedish naval defense as the lock of the baltic sea. Still today it hosts a big part of our fleet and training of the Swedish navy. The town is also known for the fact that in 1981 a Sovjet submarine called U137 by mistake ran aground outside the city.

The reason why a Sovjet submarine were so far inside Swedish waters is still not official I think. The Sovjet captain was blamed for navigational mistakes. He should of course not have been that close to Sweden said the Sovjet officials. But given today's technology it's not possible to navigate that badly so the submarine was clearly there because they ordered it to be there. Embarrassingly though it ran aground.

Ericsson also has an office in this town. Surprise, surprise! :-)
